2013 is shaping up to be a good year for old artists as eight of the highest earning tours from the first half of the year belong to bands that were around more than twenty years.  Classic rock legends Fleetwood Mac boasted the fourth-highest earning tour, while 80s favorites Bo Jovi topped the list.  Bruce Springsteen, the Rolling Stones, and The Who are on the list, as is Beatles legend Paul McCartney, Cream guitar legend Eric Clapton and Buffalo Springfield guitarist Neil Young.  The only two acts on the list that weren't around in the 80s are the Dave Matthews Band and Muse.  Check out the full list below, as compiled by Pollstar Magazine.
